摘要： PROBLEM TO BE SOLVED: To provide a practical method which forms a resin film on the inner surface of a substance having 3 or more openings, without rotating the substance, using fluid resin powder, to sweep residual resin.SOLUTION: An inlet pipe and an outlet pipe are connected to one of the openings, an outlet pipe is connected to other openings, respectively, and the fluid resin powder is flowed on the inner surface to form the resin film. A flow control valve is arranged in a conduit running from each opening to the outlet pipe to control the flowing amount of the fluid resin powder, so that the resin film having uniform thickness is obtained. When the resin film is formed, the flow of the fluid resin powder is stopped, and then air is blown in from the inlet pipe to sweep the residual resin powder. If the resin powder is accumulated, a blowing pipe for blowing away it is arranged in the outlet pipe to sweep accumulated resin powder.

解决方案：入口管和出口管连接到一个开口，出口管分别连接到其他开口，流体树脂粉末在内表面上流动以形成树脂膜。 在从每个开口到出口管的管道中布置有流量控制阀，以控制流体树脂粉末的流动量，从而获得具有均匀厚度的树脂膜。 当形成树脂膜时，停止流体树脂粉末的流动，然后从入口管吹入空气以扫除残留的树脂粉末。 如果树脂粉末积聚，则在出口管中设置吹扫吹管，以吹扫积聚的树脂粉末。 版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method which enables the formation of a coating film having a uniform thickness, even if a thick film, on uneven parts such as teeth parts of a material to be coated (gears, or the like).
SOLUTION: In the step I, an electrostatic powder coating is carried out on teeth parts 2 of gears and spline shafts 1 to form a primary powder layer 3a, in the step II, the powder layer at teeth tips 2a is scraped and vacuumed to be removed at the same time, in the step III, the electrostatic powder coating is carried out on a whole surface to form a secondary powder layer 3b, and in the step IV, the coating film 5 is formed by induction heating. In such a method, a coated article(coated gears, or the like), wherein the coating film 5 having the uniform thickness on uneven parts is formed, can be obtained. In the electrostatic powder coating, for example, a powder coating material based on a thermoplastic resin such as a nylon based resin can be used. A thickness of the coated film may be about 150-200 μm. A ratio of a coating weight (g/m
2 ) of the primary powder layer to the coating weight (g/m
2 ) of the secondary powder layer is about 20/80-80/20 when a total coating weight of the powder layer is 100.

摘要： PROBLEM TO BE SOLVED: To obtain a practical method and equipment that form a resin film by pushing fluid resin powder into the inner surface of a piping component and cleanly remove remaining resin powder.SOLUTION: An air blowing port is provided in the lower part of a hermetically closed fluid tank and a flow control valve and an inlet pipe reaching the inside of the resin powder are provided above the fluid tank. A shut-off valve, a blow valve, and a connection port are provided downstream of the inlet pipe and connected to the piping component. The piping component is connected through an outlet pipe to a dust collector for recovering the resin powder. When the flow control valve is opened and the shut-off valve and the blow valve are closed, air blown from the blowing port is discharged to the atmosphere from the flow control valve through the resin powder, thereby making the resin powder into a fluid state (fluid resin powder). When the shut-off valve is opened while decreasing the flow rate of the flow control valve to increase the pressure in the fluid tank, the fluid resin powder is pushed into the inlet pipe and flows therethrough to form a resin film. The shut-off valve is closed to stop the flow of the fluid resin powder and the blow valve is closed to make air flow, thereby blowing off the remaining resin powder to perform cleaning.
